AI Technical Summary

Benefits of technology

The enclosure is filled with a positive flow of gas. The resulting flow results in the interior of the enclosure having a higher pressure relative to the outside standard room air pressure. This enclosed positive pressure field is applied to an operation site via the aforementioned opening. In one embodiment, the opening may be of sufficient size to allow nearly the entire patient to be exposed to the positive pressure field, with the exception of the head and upper chest of the patient. In this preferred embodiment the surgical team may be enclosed in the field as well, to allow for easier access to the patient. In an alternate embodiment, the enclosure is of a size sufficient to allow only a small area of the patient to be exposed to the positive pressure field. In such an embodiment the surgeons access the operation site through several openings in the sides of the enclosure.
Both forms of the invention may be readily transported and used outside of surgical theaters to provide the benefits of the invention, as well as providing a generally sterile environment. Thus, bleeding and contamination may be controlled in the field by the use of the enclosures of the invention.

Problems solved by technology

Primary of these are the bulky and intrusive direct pressure means which usually consist of the application of direct physical pressure upon a wound by the surgeon's hand, gauze, or bandage.

Abstract

An apparatus for enclosing a portion of a patient in need of surgery to define an enclosure in which a positive air pressure is introduced to decrease blood loss during surgery. This apparatus may be used to provide a generally sterile field and to decrease blood loss during surgery.

Description

1. Field of the InventionThis invention relates to a surgical apparatus which functions during surgical procedures to reduce blood loss that would otherwise normally occur from cut or similarly exposed blood vessels, especially veins and capillaries by imposing upon these capillaries an amount of air pressure sufficient to interfere with the passage of blood through and out of the damaged blood vessels.2. Description of the Related ArtCurrently there exist several techniques and apparatuses which are used to aid in decreasing blood loss during surgical procedures. Primary of these are the bulky and intrusive direct pressure means which usually consist of the application of direct physical pressure upon a wound by the surgeon's hand, gauze, or bandage. In addition techniques exist which provide for the cauterization and ligation of blood vessels.One such means for applying direct pressure to a wound is known as a M.A.S.T. suit which is most commonly used as a military anti-shock trou...
